NYARLATHOTEP

Nyarlathotep appears as a tall dark man. His appearance in the world is said to foretell the return of the Old Ones from their imprisonment. He charms humans, humanoids, and non-magical animals by his mere presence (good alignment, save at +4; evil alignment, save at -4). Those falling under his spell either obey him or behave in a purely chaotic manner. Thus his progress across the face of the land is followed by riot, war, mass murder, suicide, and insanity. No non-sentient creature can harm him, even if controlled.

The god is believed by some students of the occult to have various guises, including a red bat-like form with three evil eyes. He can call up an army of wild beasts or mindless humans within an hour's notice (1-100 of them). Each time Nyarlathotep hits an enemy, he drains 3-30 hit points from them, which temporarily add to his hit point total for one full turn. There is a 5% chance that a continual light spell will drive this being off into the Astral Plane.
